Nice post & analysis.
And straying a bit OT: people shouldn't base their decision too much on capacity. 30-40GB is more than what you need to run OS, and it's better to keep your boot/OS and storage drives separate. Even for notebooks, unless you are using it as a DVR/Media center, or your line of work requires it, HDD space is an overrated aspect. I would prefer a 30GB SSD over a 250GB HDD, especially for a netbook.
Be sure to do research if you're looking for a netbook that supposedly comes with an SSD. From many reviews I've read, many customers have been misled or disappointed. They actually got an SDHC card soldered onto the motherboard, which performs quite differently from an actual SSD.
